Porsche 992 Turbo / Turbo S – EPA-Compliant 400 Cell Catted Downpipes

Precision Engineered for the 3.8L Twin-Turbo Flat-Six • High-Flow • Compliant • 

Introducing Our NEW 400 Cell EPA-Compliant Downpipes for 992 Turbo

The Porsche 992 Turbo and Turbo S represent the pinnacle of modern forced-induction performance. While the 3.8L twin-turbo flat-six delivers exceptional power from the factory, restrictive catalysts limit exhaust efficiency and mute the engine’s true character. Our NEW EPA-compliant 400 cell high-flow catted downpipes are engineered to reduce backpressure, enhance turbo responsiveness, and refine the exhaust signature — all while maintaining emissions compliance standards.

This upgrade elevates performance while preserving the precision expected from Porsche.

Why Upgrade to 400 Cell?

  • EPA-Compliant 400 Cell High-Flow Catalysts: Increased exhaust efficiency while maintaining compliance standards.
  • Improved Turbo Response: Reduced restriction enhances spool characteristics and throttle precision.
  • Enhanced Exhaust Presence: Deeper tone with improved clarity at higher RPM.
  • Maintained Drivability: Noticeable gains without sacrificing refinement or daily comfort.

Engineering & Performance

  • Optimized Flow Architecture: Minimizes backpressure while preserving catalyst efficiency.
  • Mandrel-Bent Tubing: Smooth internal transitions for consistent exhaust velocity.
  • Precision TIG Welding: Built to withstand extreme exhaust temperatures and sustained boost levels.
  • Direct OEM Bolt-On Installation: Utilizes factory mounting locations for seamless installation.
  • Engineered to Pair with Valvetronic Exhaust Systems

Sound Character

  • Stock Exhaust + Downpipes: Subtle increase in depth and presence with improved turbo clarity.
  • Valvetronic Exhaust + Downpipes: Sharper response, stronger turbo acoustics, and a more motorsport-inspired tone while retaining Porsche composure.

Construction & Durability

  • Premium high-grade stainless steel construction
  • High-temperature resistant 400 cell catalyst cores
  • OEM-style sensor placement for proper operation
  • Engineered for long-term reliability under high-performance conditions

Elevate the performance and character of your 992 Turbo — engineered with precision, starting at the source.

Frequently asked questions

Why buy from Vero Motorsport instead of Valvetronic Designs directly?
Our pricing is fully inclusive. All customs charges, import duties, GST, fees and Australian government charges are already covered, so the price you see is the price you pay, with no surprise bills on delivery. We are an authorised Valvetronic Designs dealer and Australia's biggest, and we extend the Valvetronic Designs 12-month manufacturer warranty to Australian customers, handled locally through us. Buying direct from overseas often means unexpected customs, GST and import fees at the door, slower support and no local warranty backing.
Are there any extra costs at checkout or on delivery?
No. Our prices are all inclusive of customs, GST, import fees and government charges. There are no surprise import bills when your order arrives.
Do you price match?
Yes. If you find a genuine Valvetronic Designs product cheaper elsewhere, we will match it. Get in touch through our Price Match page.
Is the 12-month warranty valid in Australia?
Yes. We extend the Valvetronic Designs 12-month manufacturer warranty to Australian customers, handled locally through us.
What is your returns policy?
Easy, hassle-free returns. If something is not right, get in touch and we will make it right. We keep returns simple and stress-free so you can buy with confidence.
Is this a genuine Valvetronic Designs product?
Always. Vero Motorsport is an authorised Valvetronic Designs dealer, so every system is genuine factory stock, never a copy.
Will it fit my car?
Valvetronic Designs systems are fitment specific and this listing is matched to the model in the title. If you are unsure about your exact variant, year or drivetrain, contact us before you order and we will confirm fitment. You can also browse the full Valvetronic Designs range to find your car.
How loud is it, and will it drone?
These are valve controlled systems. Open the valve for an aggressive, full motorsport tone, or close it for a quiet, refined and drone free cruise. On many cars the valve follows your drive mode, with remote or app control available on supported systems, so you get sound on demand and a civil daily drive.
Is a valve-controlled exhaust legal in Australia?
Exhaust and noise rules vary by state and are tied to your vehicle. A valve controlled system is a smart choice because you can close the valve for a quiet, compliant cruise. Always check your local state requirements before fitting for road use.
How fast is shipping?
In stock systems are dispatched quickly with tracked shipping right across Australia, to Sydney, Melbourne, Brisbane, Perth, Adelaide and everywhere in between. If a system is made to order, we will give you a clear lead time before you buy.
Do you offer support if I have questions?
Yes. We offer 24/7 Australian-based support, so there is always someone here to help before and after your purchase. Reach out any time and we will look after you.
